Marcus is the son of Jimmy Allen and the late Dana Allen, older brother of Whitney Allen, boyfriend of Serena Madison, good friend of Hunter Radley, and the arch-nemesis of Ryan Harper/Lightspeed.

Growing up as a normal child, he became a good friend of Sebastian Harper, and joined Sebastian at the grand opening of the Harper Institute of Science and Technological Fields. Pushing Sebastian out of the way to avoid being showered with chemicals, Marcus was struck by lightning and Kane's rupture wave. Gaining super speed, he approached the Legends to help them fight another speed demon like him. Stopping villains like Damien Zagan, Ryan Harper, and Rip Vega, Marcus reunited with his team to stop Ghost but was captured by the Brotherhood, later aiding Sebastian in his final attack on the Brotherhood.
